So you have jailbroken your device running on iOS 5.0.1 by using Redsn0w 0.9.10b1 or by using the jailbreak tweak called Corona 5.0.1 Untether. You may noticed that Cydia is running slowly and doesn’t add any repo and sluggish, well you may think the problem is from your iPhone well it’s not:

With the public release of iOS 5.0.1 Untethered jailbreak, too many users jailbrok their devices and began adding too much repos and downloading jailbreak tweaks, so don’t worry it is just a period of time where Cydia store is having a large traffic from iPhone users and it will be fixed very soon and Cydia will run normally to all Apple devices….Please be patient 😀
